EKPLUSIVE-MUTOH.

To all whom it may concern Be it known that l, /VILLITT ll. henna, a citizen of the United States, residing at Vacaville, in the county of Solano, State oi": California, have invented. certain new and useful improvements in l lXplosive-li lotors; and I do declare the following to be a clear, full, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part oi this application.

This invention relates to improvements in explosive motors of all kinds, the object of the invention being; to produce a sliding valve intake and exhaust mechanism doing away with the necessity 0:]? using gears, cam shafts, puppet valves, tappets, springs, etc., and producing a silent and smooth running and effective valve mechanism for the purpose.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, l accomplish by means of such structure and relative arrangement oi? the parts as will fully appear by a perusal of the following specification and claims.

On the drawings similar characters of reference indicate corresponding parts in the several views,

Figure 1 is a side elevation partly in section of my improved motor. Fig. 2 is a side elevation of the operating cam.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the crank case of the motor, the numeral 2 the cylinder thereon, the numeral 8 the piston operat lg in the cylinder, the numeral 4 the crank shaft which is connected to the piston by means oi the usual connecting rod (not shown in the drawings) in my improved structure, It provide a gear l mounted on the crank shaft 4t and connected by a silent chain 5 with another gear 6 mounted on a shaft '7 there being connected with the gear 6 a cam 8 of llTGgH- lar contour, such cam having certain points at which determined action oil? the valve mecl'ianism hereinafter described takes place,

which poin are designated on the drawings. Fig.2, as a l) c, (Z and c.

Disposed transversely across the top of the cylinder 2 is another cylinder 9 in which is movable a tubular member 10 divided into two parts by a center wall 11. The inner end of said tubular member is open and adapted to communicate with the exhaust pipe 12 of the motor and is provided in its side with a port adapted to register with a port lt in the head of the cylinder 2. The other end of the tubular member 10 is closed and. has ports adapted to communicate with the fuel inlet pipe 15 and ports 16 adapted to communicate with ports 17 leading into the head of the cylinder 2. Various points at which this communicating of ports takes place is determined by the cum 8 which is connected by a rod 18 with the tubular member 10 and the points at which the various positions are assumed are shown in Fig. 2. Home, with the revolution oi the engine, when the rod 8 reaches the point a on the cam, the exhaust port has just closed and the piston 3 is near the upper end of the cylinder 2 and ready to move downwardly. The ports 15 and 15 all move into communication as do also the ports 16 and 17 causing the fuel to be taken in through the pipe 15 and ports 5 to within the tubular member 10 and from thence through the ports 16 and 17 into the cylinder. This operation continues until the point 5 is reached on the earn 8 and at this point the piston starts on its upward or compression stroke and the ports then all move out of register with each other and the compression takes place until such time as the point c is reached. At this point the compression is complete and all the valves are closed and the ignition ialtes place driving the piston 3 downward again until the point (Z is reached On the cam 8 just before the piston 8 reaches it lowest position designated by c This opens the port 13 to the port 1 iallowing the exhaust for the full upward stroke of the piston 3 until the point a is reached again when the above described operation is repeated. As will be seen this valve structure gives a balanced sliding valve mechanism which is noiseless and does away with the objectionable features noted in. the preamble above,

While l have shown a two port mocha nism, for admitting the fuel, still in practice one port would serve the purpose ust as well and such may be used in practice if so desired.

From the foregoing description it will be readily seen that I have produced such a deice as substantially fulfils the objects of the invention set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention What I claim as new and useful and desire to secure by Letters Patent is:

l. A device of the character described comprising the combination with a cylinder, and a piston moving in said cylinder, said cylinder being provided with two ports, of a sliding tubular member provided with a division wall, said tubular member being provided on one side of said division wall with a port adapted to register with one of the ports in said cylinder, the end of said tubular member on that side of the wall being open, said tubular member on the other side l of said division wall being provided with two ports, one of said ports being adapted to register with the other port in said cylinder, and an intake pipe adapted to register ith the other of said ports in said tubular member, as described.

:2. A device of the character described comprising the combination with a cylinder and a piston operating in said cylinder, said cylinder being provided with ports, of a tubular member slidable transversely across the top of said cylinder, a division wall in said. tubular member, an intake pipe, said tubular member being provided with means on one side of said division wall for forming a communication from said intake pipe to one of the ports in said cylinder, said tubular member ha *ing a port on the other side of said division wall adapted to register with the other port of said cylinder, the tubular member on that side of the division wall having an open end, as described.

In testimony whereof I aflix my signature in presence of two witnesses.
